The subcutaneous reservoir is a new vascular access for patients on regular hemodialysis (HD). A double chamber in Titanium- Pirolytic Carbon with siliconic boreable superior caps is inserted in to a subcutaneous subclavian side, and always in subcutis connected to two siliconic catheters located in the right jugular resulting in the right atrium. The puncture of each chamber is performed with a special hemodialysis-cannula telescopically assembled on a "dilatation tube", in which a stylet is inserted. In correct sequence, the cutaneous planes and the caps are bored, dilated, and finally the HD cannula after sliding over the previous structures is positioned in the inner chamber, closing the HD circuit...

COMPARATIVE STUDY
H S Trivedi, Z J Twardowski
Improvement in double-lumen catheter usage could provide lasting, user friendly angioaccess for patients on hemodialysis (HD), especially those on home HD. These catheters are routinely locked with concentrated heparin at the end of an HD session, in a volume corresponding to the lumen capacity. At the start of the next HD session, this heparin is aspirated with a small amount of blood and discarded. The cumulative blood loss over a long period becomes significant. The authors aimed to study whether a predetermined loading dose of heparin could be used to lock the catheter, and be administered as such during the next HD session...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
